I would say Facebook, since this is the most popular platform in our country. We do have Instagram, Twitter, and whatnot, but nothing compares to Facebook's reaction feature 
Sooner you'll deny what you are saying about facebook Being the most flooded social media and too much Drama ? i almost blocking pages,groups and individual day by day because of dramas happening .
I couldn't agree with you more. Facebook has lots of users, and full of bots. I don't even know how their security team let bots create their own account. It is also turning into a piracy site since I can watch unreleased movies, anime episodes, and even series on Netflix. But, I have lots of memories there, my Fb account was created way back 2009.
